Abstract
Previous results for the measurement of T-1 as a means of monitoring t emperature have demonstrated a linear calibration with a coefficient o f the order of 1.5%/degrees C. We have studied the changes in T-1 furt her, and observe that changes in tissue perfusion are substantial cont ributors to the effects observed, and that the model of what is happen ing is complex and may not permit a simple temperature calibration.
